The thumb'sci'ew 22 isloosened topermit the desired adjustment of the guide stem C by the manipulation of the set nut 28 after which said set screw 22 is tightened to lock Said guide stem. A sheet of paper, fed toward the guide, passes between the depres-` sion finger E' and said bar'30 and is arrested by the lguide plate D. As the rook shaft 1,0 is turned 4toraise the guide (see arrow in Fig. y3) the barrel B is tilted by the spring l15 until it strikes the stop 19 on said shank 13 (see Fig. l), at which point in thef'operation the barrel is lifted. `This tilting movement of the barrel B causes thel guide plate Dl to slide 0n the bar 30 away from the edge of the Asheet of paper, thereby leaving said sheet in proper position to be grasped by grippers on an impression cylinder.

1. In a frontfeed guide for printing presses, the combination withy a rock shaft and feeding lmbar -of a lclamp adjustably secured upon said lrock shaft, a..barrel pivotal'ly'suspended beneath said clamp, a guide stem adjustable longitudinally said barf rel and provided with a dependent guide plate adapted to 'engage said feeding bar,

and a compression spring ,interposed between saidclamp and barrel, said spring v being adapted yto tilt'the barrel upon the protect by Leti 'initial upward movement of the guide;

whereby the guide plate is withdrawn from the edge rof a sheet before said plate is lifted.

2. Ina front Afeed' guide .for printing presses, the combination with arock shaft and .feeding bar of a clamp adjustably seformer lwith respect to the latter, a -stop on the clamp to limit the tilting movement of the barrel, a guide'stem slidable longitudinally in said barrel,v means to prevent the turning of said stem, a second spring, withoperating to move the stem inone direction, a nut threaded on the stem and abutting against oneend of said barrel, said nut being adapted to permit the movement of said stem by `said spring, also Yto check said move;

mentand further to shift the stem against the action of the spring, a guide plate de.

l pendingv from the stem and arranged to bear 'ipon said feeding bar, a depression fingerv on the stem to guide a sheet as it is fed t0- ward said plate, ysaid compression spring being adapted to tilt the barrel during the initial upward nio-vement of the guide, so

as to withdraw the guide' plate from the edge of said sheet before said--plateis lifted. 'In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses. I
